The term "refractory anemia" was used in 1937 by Cornelius Parker Rhoads to describe patients whose anemia did not improve after treatment with liver extract or iron salts, and this term has been used to denote patients with certain subtypes of myelodysplastic syndromes (MDS) since the 1976 and 1982 French-American-British (FAB) classifications of acute leukemias and MDS. In 2016, the World Health Organization (WHO) proposed elimination of "refractory anemia" in a more general proposal for reclassification of myeloid neoplasia...

Most patients with iron deficiency anemia are treated effectively with oral iron preparations. However, a small number of these patients are refractory to such treatments, even when the pathologic condition underlying the anemia is concurrently treated. The pathological basis for this refractoriness can be explained by several factors, including malabsorption of iron, e.g. atrophic gastritis, deficiency of other hematopoietic vitamins or minerals, e.g. vitamin B12 or zinc, other undiagnosed anemic disorders, e...

To determine whether a lower imatinib dose could minimize toxicity while maintaining the molecular response (MR), imatinib dose was reduced to 300 mg daily in 43 patients with chronic myeloid leukemia (CML) in sustained deep molecular response to first-line imatinib 400 mg daily. At the time of dose reduction, median duration of the deep response was 4.1 (interquartile range (IQR) 2.2-5.9) years; molecular response was MR(4), MR(4.5), and MR(5) of the international scale in 6, 28, and 9 patients, respectively...

The gut microbiota plays an important role in host health, in particular by its barrier effect and competition with exogenous pathogenic bacteria. In the present study, the competition of Bifidobacterium pseudolongum PV8-2 (Bp PV8-2) and Bifidobacterium kashiwanohense PV20-2 (Bk PV20-2), isolated from anemic infant gut microbiota and selected for their high iron sequestration properties, was investigated against Salmonella Typhimurium (S. Typhi) and Escherichia coli O157:H45 (EHEC) by using co-culture tests and assays with intestinal cell lines...

BACKGROUND: The accuracy of point-of-care blood glucose (BG) meters is important for the detection of dysglycemia, calculation of insulin doses, and the calibration of continuous glucose monitors. The objective of this study was to compare the accuracy of commercially available glucose meters in a challenging laboratory study using samples with a wide range of reference BG and hemoglobin values. METHODS: Fresh, discarded blood samples from a hospital STAT laboratory were either used without modification, spiked with a glucose solution, or incubated at 37°C to produce 347 samples with an even distribution across reference BG levels from 20 to 440 mg/dl and hemoglobin values from 9 to 16 g/dl...

Cancer related anemia (CRA) adversely affects patient Quality of Life (QoL) and overall survival. We prospectively studied the prevalence, etiology and the impact of anemia on QoL in 218 Indian cancer patients attending a tertiary referral hospital. The study used the sTfR/log Ferritin index to detect iron deficiency anemia and assessed patient QoL using the Functional Assessment of Cancer Therapy-Anemia (FACT-An) tool, standardized for language. Mean patient age was 51±13 years and 60% were female. The prevalence of cancer related anemia in this setting was 64% (n = 139)...

INTRODUCTION: Treatment of severe hemorrhagic shock due to acute blood loss from traumatic injuries in a Jehovah's witness (JW) trauma patient is very challenging since hemostatic blood product resuscitation is limited by refusal of the transfusion of allogeneic blood products. CASE PRESENTATION: We describe a multifaceted approach to the clinical care of a severely anemic JW trauma patient including the early administration of a bovine hemoglobin-based oxygen carrier (HBOC) as a bridge to resolution of critical anemia (nadir hemoglobin 3...

Hemopure (hemoglobin glutamer-250 [bovine]; HBOC-201) is a hemoglobin (Hb)-based oxygen carrier registered with the Medicines Control Council of South Africa. It is indicated for the treatment of adult patients who are acutely anemic, for the purpose of maintaining tissue oxygen delivery thus eliminating, delaying, or reducing the need for allogeneic red blood cells (RBCs). Hemopure is a volume expander, and circulatory volume must be carefully monitored for signs of fluid overload. Hemopure is not as effective as RBCs for restoring Hb content and concentration, but in cases of severe anemia where allogeneic blood is not an option or is unavailable, it may offer an immediate alternative for improving oxygen transport...

Data from a cross-sectional study of a clinic-based sample of older people living with HIV (PLWH; n = 100) were used to examine associations between biomarkers of physical health and neurocognitive impairment (NCI). In this sample, anemia, chronic kidney disease (CKD) stages 4-5, and hypocalcemia were associated with impairment in executive functioning or processing speed. Furthermore, participants with anemia were more likely to have CD4+ T cell counts <200 cells/mm(3) (χ(2) [1] = 19.57, p < ...

OBJECTIVE: Research supports the efficacy and safety of restrictive transfusion protocols to reduce avoidable RBC transfusions, but evidence of their effectiveness in practice is limited. This study assessed whether admission to an ICU with an restrictive transfusion protocol reduces the likelihood of transfusion for adult patients. DESIGN: Observational study using data from the multicenter, cohort Critical Illness Outcomes Study. Patient-level analyses were conducted with RBC transfusion on day of enrollment as the outcome and admission to an ICU with a restrictive transfusion protocol as the exposure of interest...

INTRODUCTION: Heart failure (HF) is always complicated with anemia and is associated with bad prognosis in this patient population. Several studies have assessed the potential role of erythropoietin-stimulating agent (ESA) in improving cardiac function and reducing the number of hospitalizations in anemic patients with HF. AIM: We performed a meta-analysis to assess the potential role of ESA in the treatment of anemic patients with HF. MATERIAL AND METHODS: A literature and Medline search was performed to identify studies with control groups that examined the efficacy of ESA therapy in patients with HF and anemia...

BACKGROUND: Incompatibility between parental platelet (PLT) antigens may lead to sensitization of mother and development of fetal and neonatal alloimmune thrombocytopenia (FNAIT) resulting in fetal thrombocytopenia. Intravenous immunoglobulin (IVIG) with or without prednisone is the most effective, evidence-based antenatal treatment for subsequent FNAIT-affected pregnancies. IVIG infusion causes hemolysis in other settings, the degree depending upon patient blood groups (BGs). STUDY DESIGN AND METHODS: In ClinicalTrials...

INTRODUCTION: The cause of the sudden infant death syndrome (SIDS) is perhaps the oldest of unsolved mysteries of medicine, possibly dating back to Exodus in Biblical times when Egyptian children died in their sleep as if from a plague. It occurs when infants die unexpectedly with no sufficient cause of death found in a forensic autopsy, including death scene investigation and review of medical history. That SIDS is an X-linked recessive death from infectious respiratory disease of a physiologically anemic infant and not a simple anomalous cardiac or neurological condition is an extraordinary claim that requires extraordinary evidence...

Diamond-Blackfan anemia (DBA) is a rare congenital disorder characterized by pure erythrocyte aplasia, and approximately 70% of patients carry mutations in the genes encoding ribosomal proteins (RP). Here, we report the case of a male infant with DBA who presented with anemic crisis (hemoglobin [Hb] concentration 1.5 g/dL) at 58 days after birth. On admission, the infant was pale and had tachypnea, but recovered with intensive care, including red blood cell transfusions, and prednisolone. Based on the clinical diagnosis of DBA, the father of the infant had cyclosporine-A-dependent anemia...

BACKGROUND: Little attention has been placed on the unique iron demands that may exist in women with multiple gestations. This merits attention because iron deficiency (ID) during pregnancy is associated with adverse pregnancy outcomes that are known to be more prevalent in multiple births. OBJECTIVE: We characterized longitudinal changes in iron status across pregnancy in a cohort of healthy women with multiple gestations and identified determinants of maternal ID and anemia...

Hemotropic mycoplasmas in dogs, such as Mycoplasma haemocanis, have been described worldwide. Recently, these pathogens have been reported to be causative agent of zoonosis. It is known that its transmission may occur through the action of blood-sucking arthropods (e.g. ticks or fleas), through blood transfusion, contaminated fomites and/or transplacentally. In Brazil, M. haemocanis is present in practically all regions and the tick Rhipicephalus sanguineus sensu lato is suspected the main vector. In the municipality of Campo Grande, state of Mato Grosso do Sul, there is little information about infection of dogs by M...
